We suggested a method for localization of ischemic lesions from difference integral body surface potential maps (IBSPMs) computed by subtraction of IBSPM without manifestation of ischemia from the IBSPM during ischemia that can be obtained at rest and during the stress test. In this work the possible changes in IBSPMs of healthy subjects with increasing HR were studied. BSPMs were measured duri...

Sponges have a remarkable capacity to rapidly regenerate in response to wound infliction. In addition, sponges rapidly renew their filter systems (choanocytes) to maintain a healthy population of cells. This study describes the cell kinetics of choanocytes in the encrusting reef sponge Halisarca caerulea during early regeneration (0-8 h) following experimental wound infliction. Subsequently, we...

The Pass Peak Formation is a Tertiary basin-flank deposit exposed throughout much of the Hoback Basin; a depression physiographically distinct from, but structurally continuous with, the northern Green River Basin. Two lithofacies of the Pass Peak Formation are identified. A northern quartzite conglomeratesandstone facies, possibly as thick as 3200 ft, intertongues southward with a sandstone-si...

Global declines in amphibians likely have multiple causes, including widespread pesticide use. Our knowledge of pesticide effects on amphibians is largely limited to short-term (4-d) toxicity tests conducted under highly artificial conditions to determine lethal concentrations (LC50). We found that if we used slightly longer exposure times (10-16 d), low concentrations of the pesticide carbaryl...

The araneid spider genus Alpaida O.P.-Cambridge, 1889 has, until now, 148 described species (WSC 2015). The males of A. nigrofrenata (Simon, 1895), A. machala Levi, 1988, and A. cisneros Levi, 1988 are described here for the first time. A. moka Levi, 1988, based on female specimens, is synonymized with A. xavantina Levi, 1988, based on the study of specimens of both sexes. I.L.F. de Magalhães (...

passiflora species were known by their anticonvulsant, anxiolytic and sedative activities. the aim of this study was to investigate the chemical composition of the most active leaf extract of passiflora caerulea l. grown in egypt. the ethanolic extract of the leaves exhibited higher activity than aqueous extract as anticonvulsant (63% potency relative to carbamazepine), analgesic (70% potency r...
